In Fig. REF , we show a comparison of our approach with the conventional Shift and Sum refocusing method [1]}. Thanks to the regularization used in the layer construction (see Section REF ), the light field is extended angularly, which allows rendering images with reduced angular aliasing as in Fig. REF (b). As shown in Fig. REF (c), the aperture can also be taken larger than the baseline of the input Light Field from which the FDL model is constructed. The possibility to change the shape of the aperture also gives better control over the bokeh (i.e. the quality of the out-of-focus regions).
